EXHAUST -HEAD.

SPECIFICATION forming part of LettersPatent No. 791,773, dated June 6, 1905.

' Application filed January 1A, 1905. Serial No. 241,161.

To all whom it may concern.-

of the city of Detroit, in the county of Wayne and State of Michigan, have invented certain Improvementsin Exhaust -Heads,- of which the following is a specification.

The principal object of this invention is to collect lubricatory oil carried with the ex-' haust-steam from a steam-engine; and it consists in improved means whereby the, exhauststeam carryingthe oil in escaping is brought into contact with surfaces which cause it to take a circuitous passage, whereby the globulesof oil are aggregated and allowed to flow with any condensed steam by the force of gravity to acommon receptacle, from which they are drawn for separation.

In the further description of the said invention which follows reference is made to the accompanying drawings, forming a part hereof, and in which Figure 1 is a vertical central section of" the improved exhaust-head; and Fig. 2, a crosssection of Fig. 1, taken on the dotted line 00 w, except that the upper portion is torn away.

Referring now to the drawings, it will be seen that the shell or casing of the apparatus is in two parts or sections 1 and 2, which are flanged and connected by bolts 3. The lower end also of the section 2 is flanged in order that it may be secured to the exhaust-pipe (not shown) leading from a steam-engine. A portion of the wall of the lower section 2 is made double, whereby an annular open-top chamber 5 is formed for the collection of condensed steam and any oil with which the steam is charged. A nozzle 7, leading from the annular chamber, is preferably interiorly threaded, and into it is screwed a pipe (not shown) for draining the said chamber of water and oil. The upper section 1 of the shell or casing isannu'lar, and the central opening 9 has an area considerably in excess of that portion of section 2 which first receives the exhaust-steam. The upper end of thesection 2 is flared outwardly to increase its diameter and transverse area and forms, with the annular section 1, the chamber 8, in which a large portion of the exhaust-steam is condensed and i V the globules of oil mechanically mixed with Be it known that I, ARTHUR J. GREENAWAY,

the steam aggregated by means of a peculiarly-constructed baffle-plate, which as an entirety is denoted by 10. This baflie-plate consists of three members: first, a series of separated dished concentric rings 6, which are held together by ribs 0, extending radially from a central hub d. The outer dished ring is flanged, and the flange is interposed between the sections 1 and 2 and held in place by the bolts 3, before referred to. The second member of the baflie-plate consists of a series of separated dished rings 6, held together by ribs f in a manner similar to the first memher, which rings are inverted in position and cover the annular spaces between the lower rings. The effect of the two series of dished rings arranged as described is to cause the exhaust-steam in escaping to take a circuitous passage and come in contact with a large area of oil collecting surface. To prevent the lower rings 5 holding water and oil, they are provided with a few small holes 9, as shown. The third member of the baffle-plate consists of an inverted-cup-shaped plate 12, of a larger diameter than the inner wall of the lower section of the casing or shell 2 and situated di-- rectly over it. It is provided with a bolt 13, whereby the three members. of the baffleplate are secured together. The vertical distance between the edge of the inner wall of the section 2 and the inverted-cup plate, to-' gether with the enlargement of the outer wall,

uncondensed steam then passes to the baflieplate, where further condensation takes place, the water, with the oil mixed with it, falling to the chamber 5,- and the uncondensed steam escaping through the central aperture 9 in the section 1 of the head. Owing to the large surface with which the exhaust-steam has to come in contact, very little of the oil carried with the steam is lost. v

The baflie-plate being practically a single element, the whole apparatus consists of but three parts, which may be easily and rapidly connected by the bolts 3, and is adaptable to any exhaust-steam pipe.

I claim as my in-vention 1. In an exhaust-head, the shell or casing thereof formed in two flanged parts or sections, the lower section having an annular water and oil collecting chamber with an outlet therefrom, combined with a baffle-plate with circuitous passages therein which is interposed between the flanges of the two sections, bolts which pass through the two sections and the bafilemlate, to hold the three parts togather, and a concave plate to conduct water of condensation falling from the bafiie-plate to the water and oil collecting chamber, substantially ,as specified.

2. In an exhaust-head, the shell or casing thereof formed in two parts vorsections, the lower part or section having a water and oil collecting chamber with an outlet leading therefrom, combined with a baffle-plate which is interposed between the upper and lower sections of the head, the said baffle-plate consisting of a series of dished, separated rings suitably tied together, a similar series of rings situated over the first series, in an inverted position and covering the spaces between the lower rings and a deflecting-plate situated under the lower series of rings adapted to conduct Water of condensation to the said Water and oil collecting chamber, substantially as specified.
